I ALWAYS APPRECIATE THE PEOPLE who work on holidays. I just ran out to pick up a missing ingredient for the green bean casserole I’m making tomorrow (Christmas isn’t at our house this year, so I’m not doing the usual turkey-and-lamb routine). The store was packed, and it reminded me of one Christmas several years ago where I had to run out and get something on Christmas Day. The quickie-mart cashier was very surprised when I thanked her for being there — apparently, nobody does that much. But to everybody who’s working today, or who will be working tomorrow: thanks for keeping the world going while the rest of us celebrate.
